METAL WHEEL-HUB.

'To all whom it may cof/wem:

Be it known that I, GEORGE MANNEs, a citizen of theUnited States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Metal Wheel-Hub; and I do hereby declare the followin to be a full, clear, and exact description cfg the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had tothe accom anying drawings, and to the figures of re erence marked thereon, which form a part of this specilication.

My invention relates to metal wheels of the class designed to be used in connection with velocipedes, baby-carriages, tricycles, etc., and has particular reference to the hub construction of such wheels and the manner of securing the spokes thereto.

TheV object ofmy invention `is the provision of ai sim le, im roveduand highly eiiicient wheel of) this c ass, which is easyI and inexpensive of manufacture, and`strong and durable in itsvconstruction whereby to enhance the racticability and commercial value thereof).

The invention is fully described in the.

afin Fig. 2. Fig. 4 is an elevation of the same with the reinforcing barrel in position thereon. Fig. 5 is a partial section of the hub on the line ag in Fig. '3, one {iange being removed, and Fig. 6 is a vvside view of the reinforcing barrel.

Referring to the drawings, 1 designates the sleeve or tube which constitutes the body of the hub and car-ries at 'its ends .the spoke securing 'flanges 2, 2.` These flanges are preferably stamped fro1n sheet metal, and theblank from which each is formed is preferably-of disk-form and is provided with a central o ning, which is enlarged and has its wa broadened or flanged as at 4, to receive and form a suitable bearing for the sleeve 1. The outer marginal portion 5 of the blank is pressed in the same direction as the flange 4 to combine with such Specification of Letters Patent. Patented J al1. 18, 1910. Application led May 26,

part to form an annular recess 6, the depth of which, relative to the portion 5, is preferably, but not necessarily', equal to substantially half the thickness of the wire forming the spokes 7' for the purpose hereinafter described.

8 designates embosses which are formed at intervals around the portion 5 of the flange and provide radial recesses preferably of sem-i-circular form in cross-section on the side thereof o posed to the recess 6. The recesses formedibyl the embosses or depressed portions 8 extend entirely across the portion '5 of the flange and have their inner ends opening into the recess 6, due to the shearing of the inner ends of such embosses from the outer wall of the recess 6, as shown at 9. TheV spokes 7 are formed in spokes being formed from a sing e iece of wire by ben ingthe same inthe middle, thus formingl the integral loop portion 10. These spokes ave theirloops seating in the annular recess 6 and their radiant portions extended outwardly through thesheared inner airs, two

en'ds of the embosses 8 and lying in the reagainst lateral movements b the' walls of the radial recesses in whicht eyY seat.

In order to prevent lateral pivotal movements of the spokes relative to their anges when their outer ends are not secured to the wheel Irim, and Athus facilitate an assemblingof the parts during manufacture, the free end ofeach inturned portion lof the lianges is formed with a serles of ears Orlugs l1,

which are intended to be bent outwardly overV against the loo s 10 of the spokes to hold such loops rigi ly seated in the recess 6, as shown. f

In assembling the parts of the hub the flanges 2 are preferably placed thereon, with the recesses 6 thereof disposed inwardly, thus leaving the bulged sides of such recessed portions to coperate with the ends of the sleeve to form a broadened bearing surface for a s indle nut. The inward movements of the danges on the sleeve 1 are pre`- vented by shoulders 12 formed on the sleeve,

as is customary in such cases, and theout- Ward movements thereof are prevented by an expansion of the ends of the sleeve within the outer portions of the flange bearings, as shown. For the purpose of preventing a relative turning of the flanges 2 and the sleeve, the inner end of the bearingportion 4 of each flange is provided with an ear or lug 13, which enters a notch 14 in the contiguous shoulder 12 of the sleeve.

15 designates a supplemental or reinforcing sleeve or drum, which encircles the sleeve 1, and is preferably of suitable diameter for its ends to abut flanges 2, at the inner ends of the embosses 8, as shown in Fig. 4. The ends of the sleeve l5 are notched, as ati 16, in suitable position to aline with the inner open ends of embosses 8, and to receive the contiguous sides of the spokes 7 thus adapting the sleeve to prevent relative rotary movements of the flan es of a hub..

I wish it understoo that my invention is not limited to any specic construction and arrangement of the 'parts except in so far as such limitations are specified in the claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is,-

1. In a wheel, the combination of a hubsleeve having spoke securing flanges at its ends, spokes attached to said flanges and having portions exposed interiorly of the flanges, and a supplemental sleeve encircling the rst mentioned sleeve and having its ends provided with notches for receiving the contiguous sides of the exposed portions of the spokes.

2. In a wheel, a sleeve formed with an annular shoulder in spaced relation to each end, a spoke engaging flange at each end of the sleeve surrounding the latter, the free ends of the sleeve being flared outwardly to form shoulders to engage the spoke flanges, said flanges being formed with radial embosses, sa1d embosses terminating at a circular recess formed at the inner ends thereof, the inner end of each spoke flange being formed with spaced ears, a series of spokes connected at their inner ends in airs, said spokes having their connected en s disposed in said circular recesses and engaged by said ears and having their portions adjacent said connected ends engaged in said embosses.

3. In a Wheel, a sleeve, a spoke engaging flange at each end of the sleeve, each of said flanges being formed with an annular recess and a series of radial embosses, a series of spokes connected at their inner ends and having their connected ends disposed in said circular recess,l and a supplemental sleeve encircling the first named sleeve,A said supplemental sleeve being for engagement with each of said spoke engaging flanges to prevent rotative movement thereof with respect to each other.

4. In a wheel, a sleeve, a spoke engaging flange at each end of the sleeve, each of said flanges being formed with an annular recess on its inner side face and with a series of radial embosses which are struck outwardly from said flange and which are disposed at the inner side face of the flange, and a series of spokes connected at their inner ends and having their connected ends disposed in said circular recess, the inner end of each spoke flange adjacent said recess thereof being' formed .with ears which are engaged about said connected ends of the pairs of spokes.

5. In a wheel, a hub sleeve having spoke engaging flanges formed with a central recess and embosses, spokes engaging in said recess and having portions arranged in said embosses, and a supplemental sleeve having its ends extending in said recess and having spaced notches to receive said spokes at their points Where they lie in said recess.

6. In a wheel, a sleeve, a spoke engaging flange at each end of said sleeve, each of said flanges at their inner faces being formed with a central recess, the material beyond said recess being bowed radially to form a series of spoke sockets, the inner end of each bowed portion being sheared so as to establish communication between the spoke sockets and said recess, a'nd spokes arranged in pairs connected at their inner ends, said spokes seating in the spoke sockets and having their connecting portions arranged in said central recess.

In testimony whereof, I Ahave hereunto signed my name to this specification in the presence of two subscribing witnesses.
